RDP - Change Resolution in open Connection

Hey Guys,
I'm currently reviewing your application. First Impression: This tool is awesome. I'm currently / was until yesterday using another popular RDP Tool with half the features for the doubled price.
However, there is one feature I'm currently missing / haven't found:
I'm using RDM on Laptops which get disconnected and connected to several external Displays through the day. My expensive featureless old RDP Tool had an option not only to rescale the RDP Window (increase or decrease the full resolution window) but to change the resolution IN the RDP-Session itself fitting to the new window.
I experimented with the SmartSize Option in Session Options, the advanced view fit embedded option in Program Options Advanced and enabled RDP advanced authentication features. However I was unable to find the desired behavior. I'm currently using a workaround: I click reconnect on every single active session. The new session fits to the new windows sizes and resolutions.
I tried embedded and external RDP Windows. My Clients are Win7 with sp1 and without sp1 64bit. I'm using the latest enterprise trial version. (6.0.0.0?)
Q1: Is there a default option for my desired behavior?
Q2: Is there a way to reconnect ALL active RDP Sessions that are in different groups?
Q3 (offtopic) Is there a way to change hotkeys? (like CTRL SHIFT P for Screenshots)


Keep on the great work,
